# tre
> A LLVM backed Go compiler.
`tre` is built in Go and can compile a subset of Go code to LLVM IR. Clang is
used to compile the IR to an executable.
## Building
```bash
# Build tre and run a test program
go build ./cmd/tre && ./tre -d ./compiler/testdata/fib.go && ./fib
```
## Example
Example program that calculates the fibonacci sequence.
```go
func fib(num int) int {
if num < 2 {
return num
}
return fib(num-2) + fib(num-1)
}
func main() {
printf("%d\n", fib(34))
}
```
More examples of what's possible can be found in the [compiler testdata](https://github.com/zegl/tre/tree/master/compiler/testdata).
